Seeing how the game isn’t out yet and we don’t know what the settings are, I’m not going to agree with this non-article that it’s always streaming that much data. FS2020 had different settings that you could put in, caching levels, caps, and more. I highly doubt it’s constantly streaming that much.
As for RAM, disagree. In the case of games, it makes no sense to keep reading and writing from disk when there is ram available. Store it in RAM so it can be accessed quickly. The key is if the application releases RAM when the OS requests it to be released, or there is pressure. If I’m playing a game with 4k textures I 100% would rather have as many of them loaded into RAM when playing to make a smoother experience than constantly hitting my disk, which is on the thousands of times slower. I have 64GB just sitting there, I want them to use it.
